The LLF lattice is morecompact than the YLF crystal and favours an absorption andemission shift of the main peaks due to crystal field strength.The red and blue shifts of the emission bands towards to lower(and higher) energy are different for the transitions from 4f3and 4f25d levels. The 4f3 transitions have smaller shift (~5 timessmaller than the shift of the 4f25d) due to 5s25p6 closed-shellshielding effect. On the other hand the 4f25d transitions aremore susceptible to lattice change. The effect of the crystallinefield was compared for both lattice. The result shows that theseemission bands from 4f25d configuration always shift to lowerenergy when substituting the Y3+ by Lu3+ (i.e., the last one hasthe ionic radius 5% smaller than Y3+). 2006 artículo científico 1678-5428 https://www.redalyc.org/articulo.oa?id=81040112 en http://www.redalyc.org/revista.oa?id=810 Exacta application/pdf Universidade Nove de Julho Exacta (Brasil) Num.1 Vol.4 |
